JAKARTA - Smoking habits have many negative impacts on the body. In addition to damaging the lungs, smoking can also have an impact on causing hair loss.

A 2024 study published in the Journal of Cosmetic Dermatology, shows that smoking up to 10 sticks a day can increase the chances of hair falling out. Cigarettes can inhibit blood flow to the hair, which causes them to experience loss.

"It (smoking) limits blood flow to hair follicles by causing vasokonstriction or narrowing of blood vessels," said cosmetologist, Dr. Pratiksha Jain, quoted from Healthshots, on Wednesday, March 12, 2025.

Just like other body parts, hair follicles also require oxygen and nutrients for the body. If blood circulation is disturbed, the hair follicles will weaken.

Toxic chemicals in tobacco can cause damage to deosyribonucleic acid or cell DNA in hair follicles. After the hair follicles lose strength, the hair is thinning and eventually the hair goes out.

"Cooks damage follicle cells and disrupt the natural cycle of hair growth," he added.

Then Doctor Jain said that quitting smoking can allow hair to not fall out and grow healthier. However, other treatments on the hair are still needed so that the growth opportunities for return are more optimal.

"The reduction in hair loss can occur within months of stopping, as inflammation decreases and oxygen supply increases," he said.

"However, using supporting care such as minoxidil, PRP therapy, and a nutrient-rich diet can increase the maximum chance of growth again," he concluded.
